My invention relates to the construction and mounting of hinged dumping doors such as are used on hopper or other species of dump cars.

t The objects of my invention are to provide a strong and rigid door "structure an to so hinge it to the car frame that the door may be .ap lied or removed without dimeulty. I o desire to provide means for .e adjusting the various hinge elements Iso that in the event that .the door or, the door supporting beam is not accurate, the hinges may be aligned nevertheless to permit free swingin .of the door..

ese and other detailed objects of my invention are secured bythe construction illustrated in the accompanying drawings,

in whichy Figure-1 is a top view of the door and adjacent car structure.

' igure 2 is a side view of the door and adjacent car structure.

Figure 3 is in part a transverse section through the doors and the adjacent parts of a typical. hopper car upon. which the doors are mounted, taken on line 3--3 of Figure 1, and in part a section through the car showing a door in end elevation.

-The main face of the door .consists ofa .30 plate 1. The forward edge of the door is preferably 'formedby the top flange -2 of a lone-piece casting or beam having' a vertical web 3 'and a lower horizontal-flange 4. This beam is deepest at its ends and middle rtions and decreases in depth from its middle portion outwardly, being most shallow a short distancerfrom its ends. Atintervals along the beam, recesses 5i are provided to Y receive the ends of door st iiening members `tu `6 which are secured to the beam through flange 2 and throu h suitable vertical ribs Intermediate the I are provided between the face of web'3 op ite 'il i 4 land the edge of horizontal gige e outer edge of flange 2 is preferabl inclined downwardly to form an, extende meeting surface for the corresponding edge of an f 2 provided on the an e. recesses 5 reinforcing r1 adjacent door. Web 3 is inclined forwardlyv from the middle to the ends of the door.

A vertical rib 8 reinforces each end of the door and has the end stifening channel- 6 secured thereto. Rib 8 and channel 6 form a'door end wall below the top surface of the door which serves to close the gap between the door and the car end floor.

Each stilening member 6 and 6* carries 'a hinge butt element9, the ends of which dare bifurcated to' receive between them the eye of an eye-bolt 10'and a removable hinge piull extends horizontally through the eye of the bolt and theears of butt 9.

In mounting the door upon the car, the

eye bolt 'may' be swung to-'any necessary angle and extended through the supporting elements of the car frame. ,In the accompanying illustration in Figure' 3, 'the.Supporting element of the cat frame is indicated as a portion of a cast steel underframe including a main vertical flange 12, an upper horizontal` flange 13, a lower horizontal flange 14, and anV innervvertical flange 10,.,

The, lower surface of horizontal ilangefl,

is provided with bosses 17 at intervals through which rhole's extend for .the reception of eye-bolts 10. These bosses 17 vare machined and each eye-bolt is provided with a shoulder 18 .fitting against the machined surface of a respective'boss 17. A nut 20 l-on the shank of eye-bolt 10 engages the Ina-f chined upper face of a boss 23 on the underframe flange 13 and constitutes adjustable means for securing the eye-bolt in place from the upper side of the horizontal flange'l 13 of the car frame element.` l

This ,arrangement facilitates the application of the door to the frame and its removal' or replacement for repairs. All of the faces ofbosses 17 `'may be machined at onetime and without necessarily machining any other.

underframe surface.l Thefaces of bosses 23 may be machined similarly. The hinge butt 9 exte'nds rearwardly ofthe door plate 1A and is arranged so that the hinge pin .11' and eye-bolt frame member and thevdoor. and replaced4 independently lof the other hinge elements. Furthermore` in the event .of any distortion or other inaccuracies in the door parts or Ain the frame element 13,' nuts .20 'maybe adjusted to secure alignment of all the rhinge' pins 11v throughout thelength of the door. If desired, washers` 19 may be inserted between the shoulder 17* on the eye bolt and the boss' 17 on the frame element in the event that itis necessary to drop the eyee5 1 10 may-beremoved fromv the loo` los

bolt and hinge somewhat in order to preserve the alignment referred to.

Each end of the beam located at the inner edge of the door has a projection 21 extending beyond t-he end of the door by which the door' may be secured to the door` operatlng mechanism (not shown) through a link 22 or other suitable connection.

Some of the elements of the car structure illustrated in my present drawings are described and claimed in my copending application Serial'No. 79,782, filed January 7,

ving transversely of said beam.

2. In a dumping car door, a beam extending along an edge of the door and including a vertical flange substantially paralleling the 'door edgeI but spaced therefrom, there being openings in said flange at intervals along its length, and door stifening members extending transversely of said beam and through said openings.

3. In a dumping car door, a beam extending along an edge of the door and including a vertical flange substantially parallel-v ing the door edge but spaced therefrom, there being openings in said liangeiat intervals along its length, door stilening members extending transversely of said' beam and through said o nings, and elements extending transverse y of said 'beam and bracing said edge from said flange intermediate to said stifl'ening members.

4. -In a dumping car door, a door beam extending along but spaced from a door edge, said beam being provided with openings at intervals to receive door stiffening members extending transversely of sai beam, and transverse elements at intervals along said beam between said openings and bracing the adjacent door edge from said beam.

6..
